经过人工选择的驯化植物改变了植物的化感作用和养分含量。以这些植物为食的昆虫，以及攻击这些昆虫的拟寄生虫，被迫适应这些变化，在这里，我们提出了两项研究的结果，一项涉及草食动物粉蝶（Pieris rajiang）（Lep.：粉蝶科（Pieridae）及其寄生蜂Cotesia glomerata（Hym.：Braconidae），另一种涉及食籽甲虫Zabrotes subfasciatus（Col.：Bruchidae），寄生于Stenocorse bruchivora（赞美诗：茧蜂科）。在这些研究中，我们研究了植物驯化对植食性和寄生性的表现和寄生性的寄主定位行为的影响。我们测试的假设，作为植物驯化的结果，品种提供了更高质量的资源，食草动物和他们的寄生比他们的野生亲戚。这两项研究的结果表明，总体而言，草食动物和寄生蜂的性能是高于栽培植物物种比野生物种。此外，选择实验表明，寄生蜂更吸引栽培品种比相关的野生植物，栽培植物的吸引力较高，这表明这些寄生蜂在寄主定位过程中使用的挥发性植物化学物质没有丢失或减少，作为植物驯化的结果，我讨论母鸡：自然选择可能对拟寄生物起作用，使其将寄主定位在其性能高的植物上。(C)北京：科学出版社.
Domesticated plants which have been the subject of artificial selection have altered allelochemistry and nutrient content. Insects that feed on these plants, as well as the parasitoids that attack these insects, have been forced to adapt to these changes, Here we present results from two studies, one involving the herbivore Pieris rapae (Lep.: Pieridae) and its parasitoid Cotesia glomerata (Hym.: Braconidae), and the other involving the seed eating beetle Zabrotes subfasciatus (Col.: Bruchidae) which is parasitized by Stenocorse bruchivora (Hym.: Braconidae). In these studies we examined the effects of plant domestication on herbivore and parasitoid performance and on the host location behavior of parasitoids. We tested the hypothesis that as a result of plant domestication, cultivars provide a higher quality resource for herbivores and their parasitoids than their wild relatives. Results from these two studies show that, overall, herbivore and parasitoid performance was higher on cultivated plant species than on wild species. Furthermore, choice experiments revealed that parasitoids were more attracted to cultivars than to related wild plants, The higher attractiveness of cultivated plants suggests that the volatile phytochemicals used by these parasitoids during the process of host location have not been lost or reduced as a result of plant domestication, me discuss hen: natural selection may have operated on parasitoids to locate hosts on plants on which their performance is high.
